JEWELERS CUTTING-PLIERS.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed November 30,1906. Serial No. 345,693.

To all whom it may concern:

of Bristol and State of Massachusetts, have invented certain new anduseful Improvements in Jewelers Cutting-Pliers, of which the followingis a specification.

This invention relates to pliers, which may be used as cutters, forjewelers or silversmiths use. Its object is to improve the constructionof such pliers so that the same can be used with the minimum shifting ofposition both for gripping and cutting wire or other forms of metal. Inorder to accomplish this object I provide the jaws of the pliers withgripping members having extended surfaces wherewith to grasp the workwithout cutting the same, and on either or both sides of the grippingmembers I form the jaws with cutting edges extending laterally. Therebythe tool may be changed from a gripper to a cutter by simply moving it aminute distance toward one side or the other.

The preferred embodiment of my invention is shown in Figure 1 whichrepresents pliers in elevation with their jaws closed. Fig.

separated. Fig. 3 represents a perspective view of one of the jawsdisconnected from the other. Fig. 4 represents a section of one of thejaws, showing the manner in which the gripping piece is secured thereto.

The same reference characters indicate the same parts in all thefigures.

The pliers consist in the usual manner, of jaws a and b pivoted by astud c and having respectively, the handles d and e. As these pliers areintended for jewelers or silversmiths use, by whom fine work is done,they are comparatively small, and their full size is approximately thatshown in Figs. 1 and 2. The pliers have extended flat gripping'surfacesf and g which close against each other over an extended area, and areknurled or roughened, as shown in Fig. 3. Extending laterally from theouter edges of the gripper members are sharp cutting edges 72. and 0).These edges are formed on the jaws by cutting away the latter at a sharpangle with their external surfaces, and their direction is transverse orlateral with respect to the path in which the jaws travel whenapproaching or receding from each other. There may be one or two cuttingedges on each jaw, that is, the cutting edges may extend only on oneside of the gripping surfaces instead of on both sides, but it is of theessence of the invention that they extend laterally instead of towardthe pivot, and it is preferable that they be on the line of the extremeouter edges of the gripping surfaces.

It is possible to make the gripping surfaces on integral portions of thejaws, but I prefer to form them as shown in Fig. 4. As seen in thisfigure, one of the surfaces, as g, is formed upon a block is set into arecess in the jaw b and firmly secured therein by any approved means.The co-operating surface f is formed on a similarly constructed andmounted block secured in the jaw a.

It will be seen that by the arrangement of the cutting edges directlybeside and in line with the extremities of the gripping surfaces, thetool need only be shifted by a minute amount to change it from a cutterto a pair of nippers or vice versa, and that there is no necessity ofchanging the angle of the tool with respect to the work. Furthermore,the laterally-extending ends of the cutting jaws are tapered down so asto be capable of entering very small recesses, and of cutting 2represents a similar view, showmg the aws Very accurately at the pointwhere cuts are required.

I claim 1. Jewelers pliers having jaws provided with meeting grippingsurfaces and cutting edges extending laterally in line with the outeredges of the gripping jaws.

2. Jewelers pliers having jaws movable toward and from each other andprovided with cuting edges transverse to the direction of such motion,the jaws having also gripping surfaces of extended area.

3. Jewelers pliers having jaws provided with meeting gripping surfacesand cutting edges extending laterally on each side of the grippingsurfaces.

4. Jewelers pliers having jaws movable toward and from each other, andprovided on their extremities with transverse edges for 10s cutting andwith intermediate wide surfaces for gripping.

5. J ewelers pliers having jaws formed with cutting edges extendingtransversely to the direction in which the jaws approach and 1 o 5recede from each other, and nipper blocks having gripping surfacessecured to said jaws.

6. Jewelers pliers having jaws formed with cutting edges extendingtransversely to I 10 the direction in which the jaws approach and recedefrom each other, and nipper blocks having gripping surfaces secured tosaid jaws intermediate the extremities of the lateral cutting edges.

7. J ewelers pliers having jaws formed with cutting edges extendingtransversely to the direction in which the jaws approach and recede fromeach other, each jaw having a recess, and nipper blocks formed withextend- 10 ed co-operating gripping surfaces, set into said recesses andsecured therein to the jaws. In testimony whereof I have affixed mysignature, in presence of two witnesses.
